Question

The strength of force is expressed by
A)weight
B)mass
C)magnitude
D)longitudinal force

Answer 1

Hint: Force is the push or pull on object which results due to its interaction with another object. If two objects interact or collide, they always have a force upon each other. Force is a vector quantity. It has both magnitude and direction. Strength of force is expressed in a unit called newton.

Complete answer:
The strength of the force is expressed by its magnitude. The magnitude of force is represented in the SI unit of force called newton. One newton is force which can make an object of one-kilogram weight to move at a speed of one meter per second. Force is any interaction that changes the motion of the object. A force can cause an object to accelerate. It’s a vector quantity and has both magnitude and direction. The symbol for force is f. Therefore, the correct option is force is expressed by magnitude.

So, the correct answer is “Option C”.

Additional Information:
Force can be created artificially and the natural forces that everyone has experienced are the gravitational force and magnetic forces. These two natural forces act at a distance and they do not require any kind of contact between them. Gravity force is the reason why earth is revolving and why we are on earth. Magnetic force is the force which pulls opposite ends of magnets together and pushes the same side of magnets apart.

Note:
The weight of any object is defined as the force of gravity on the object and maybe calculated as mass times the gravitational acceleration. Weight is also a form of force. Force is expressed in different units like pounds, kilogram-force, dyne, kip or kilopond and many more.
